Exchange the CEC enclosure PCIe three-port card

Before you begin

Icon for electrostatic discharge wrist strapUse approved ESD procedures to prevent damage.

Attention:
  • This procedure is not a stand-alone procedure. Customer disruption and damage to the hardware might occur when microcode and power boundaries are not in the proper conditions for this service action.
  • If a serviceable event FRU repair directed you to this procedure, the microcode and power boundaries are already set.
  • If a serviceable event FRU repair did not direct you to this procedure, see MAP1230 Replace a FRU without using a serviceable event.
Notes:
  • All the cables and FRUs to be removed must be uniquely identified so they can be reinstalled correctly.
  • If an installed earthquake resistance kit prevents you from accessing this FRU, refer to MAP1600.

Remove the CEC enclosure PCIe three-port card

Procedure

  1. Use a replacement part with a valid DS8000® part number to ensure it has the proper firmware, VPD, and/or configuration to ensure it is compatible with the DS8000 service procedures. Attempting to use a generic POWER7® server FRU might fail and require next level of support to recover.
  2. All parts being removed must be marked or identified so they can be installed into their original locations.
    Note: Failure to do this can extend the service duration and may require next level of support assistance.
  3. Move the management console laptop from the service position Callout label 2 to the DC-UPS service position Callout label 1, as shown in Figure 1. Refer to Management console service positions (Model 961).
    Figure 1. Alternate service position

  4. Push the now empty management console tray Callout label 2 fully into the rack. See Figure 1. This allows access to the top and rear of the CEC enclosure.
  5. Use the CEC enclosure front and rear blue identify LEDs to determine the CEC enclosure to be repaired. Both blue LEDs should be solidly lit.
    • CEC control panel blue identify LED Callout label C, as shown in Figure 2
    • CEC enclosure rear blue identify LED Callout label 17, as shown in Figure 3
    Note: If both the front and rear CEC enclosure identify LEDs are not lit, use the location code listed in the serviceable event FRU list. See MAP1245 Finding FRUs by using location codes.

  6. Verify the CEC enclosure is in the power-off state. See Figure 4.
    1. At the rear of the CEC enclosure, view both CEC enclosure power supply DC GOOD LEDs.
    2. Are both DC GOOD (output) LEDs Callout label 2 blinking?
    Figure 4. CEC enclosure power supply LEDs (Model 961)

  7. Disconnect the power cables (E1-J1 and E2-J1) from the CEC with the DC Good LEDs blinking. See Figure 5.
    Note: The CEC enclosure power supply LEDs continue to blink for up to 20 seconds while internal power is discharged.
    1. Each power cable is looped once around the CEC enclosure power supply handle and secured with a cable tie.
    2. Remove the cable tie, unplug the cable and unwrap it from the handle.

  8. Observe the CEC enclosure control panel green power present icon Callout label B. See Figure 6.
    • If it is off, go to the next step.
    • If it is slow blinking, the CEC enclosure is still in the power-off state. DO NOT CONTINUE. Ensure that you have unplugged the power cables.

  9. Disconnect the PCIe cables from the PCIe three-port card you are replacing. See Figure 5.
  10. At the front of the CEC enclosure, remove the two screws Callout label A (if present) that secure the CEC enclosure Callout label B to the rack. See Figure 7.
    Figure 7. Preparing the CEC enclosure for service position

  11. Pull the CEC enclosure fully out to the service position.
    1. Hold the CEC enclosure release latches Callout label A down on both the left and right sides, and pull the CEC enclosure full out. See Figure 8.
    2. Ensure both slide rails both latch in the full out position.

  12. Remove the CEC enclosure service access cover. See Figure 9.
    1. Loosen the two thumbscrews Callout label A located at the back of the cover.
    2. Slide the cover toward the back of the CEC enclosure. When the front of the service access cover has cleared the upper frame ledge, lift the cover up and off the CEC enclosure.
    Figure 9. Removing the service access cover

  13. Remove the PCIe three-port card. See Figure 10. Unlock the card latches Callout label B, lift them into the open position, and then lift the card out of the slot.

  14. If filler plugs are present in port T3 or ports T1, T2 and T3 of the old PCIe three-port card, remove them from the old card and install them in the same port(s) of the new PCIe three-port card.

Install the CEC enclosure PCIe three-port card

Procedure

  1. Install the PCIe three-port card. See Figure 10. Lift the card latches Callout label B into the open position, lower the card into the slot, and then close the card latches until they snap into place.
  2. Install the service access cover. See Figure 9.
    1. Place the service access cover on top of the system, about 25 mm (1 in.) from the upper chassis ledge.
    2. Hold the service access cover against the system unit and slide it toward the front of the system. The tabs of the service access cover slide beneath the upper chassis ledge.
    3. Align the two thumbscrews Callout label A located on the back of the service access cover with the two holes on the back of the system chassis.
    4. Tighten the thumbscrews to secure the service access cover.
  3. Push the CEC enclosure fully into the rack until it latches in place.
  4. If the CEC enclosure was held in place with screws, install them now.
  5. DO NOT CONNECT the two power cables until directed.
  6. Connect all rear cables except the two power cables. For location codes see, Figure 5.
  7. Connect the power cables (E1-J1, E2-J1) to both CEC enclosure power supplies. See Figure 11.
    Note: The power supply DC Good green LED should blink. See Figure 4.
    1. Loop the power cable around the power supply handle and connect it.
    2. Secure the cable with the cable tie.

    Is the DC Good green LED blinking on one or both power supplies?

    • Yes, go to the next step.
    • No, ensure the power cables are properly connected. If no cable problem is found, call the next level of support.

  8. Wait up to 5 minutes for the CEC enclosure control panel green power present LED [B] to slow blink, as shown in Figure 2.
    Note: This ensures the CEC enclosure is in the power-off state.

    Is the green LED blinking?

    • Yes, go to the next step.
    • No, ensure the CEC enclosure power supplies are fully seated. The possible failing FRUs are the CEC enclosure system backplane, I2C interface card and cables, and control panel. You can also call the next level of support.
  9. Return the management console laptop to the standard service position Callout label B on the slide-out tray. See Figure 1.
    1. Slide the empty management console tray Callout label B out to the service position.
    2. Move the laptop assembly from the DC-UPS service position Callout label A to the standard service position Callout label B. Carefully route the cable bundle.
    3. Push the DC-UPS service position rails fully in.
  10. Exit this service information center parts exchange procedure and return to the procedure that sent you here.
